Every gripe I hear is about cracking heads, which is not an engine problem anymore than a lack of upkeep on the owners part. Run the 4.0L with with no oil and then complain that they tend to lock up.
I get great mileage with my 2.9 for a 4WD truck.
agreed!! as long as the coolant is changed and you dont let it overheat (and other preventative maintenence is taken care of) it should run for a very long time!!
